I design, secure, and operate production-grade Kubernetes and cloud platforms used by real companies at scale, with a strong focus on security, reliability, and automation. With 12+ years of hands-on experience, I help companies build secure, scalable, and observable infrastructure across both cloud and bare-metal environments. My expertise is not based only on certifications, but on real enterprise experience operating critical systems under real production pressure. I have worked as a Senior SRE / Platform Engineer at companies such as Thryve, Getir, HelloFresh, Westwing, and Sony, where I was responsible for Kubernetes platforms, cloud architecture, CI/CD, observability, and security hardening. What I bring to your project is not “DevOps scripting”, but true production-grade platform engineering and the best practices used in large-scale enterprise environments. Most clients come to me after their Kubernetes or cloud setup becomes unmanageable, insecure, or overly complex. I help turn those environments into clean, secure, and maintainable platforms. ⸻ Core Expertise • Kubernetes cluster design, hardening, and operations (CKA / CKS level) • Multi-cloud architecture across AWS, GCP, Open Telekom Cloud, OpenStack, and hybrid environments • AWS cloud architecture (networking, IAM, security, cost optimization) • GitOps with ArgoCD / Flux, CI/CD pipelines, and automation • Infrastructure as Code with Terraform, Ansible, CloudFormation, and CDK • Observability stacks: Prometheus, Loki, Tempo, OpenTelemetry • Container and image security: Trivy, Cosign, SBOM, distroless images • Network Policies, Pod Security Admission, runtime security, zero-trust concepts • Running stateful workloads (databases, HAProxy, storage) inside Kubernetes • Bare-metal and hybrid Kubernetes environments I also have a programming background in Go, Python, and PHP, which helps me understand application needs deeply and design infrastructure that truly fits the workload. ⸻ Certifications • AWS Certified Solutions Architect • CKA – Certified Kubernetes Administrator • CKS – Certified Kubernetes Security Specialist

Hello, I am Choudhry. I wrote the IaC for (Middle East's #1 supercomputer) GPU cluster orchestration on KAUST Shaheen III, the Middle East's #1 supercomputer (ranked 18th globally on the Nov 2025 TOP500, 2,800 NVIDIA GH200 Grace Hoppers, liquid-cooled HPE Cray EX). That's the level of GPU and LLM infrastructure I work on, on-prem and in the cloud. 📌 What I'm an expert in: 🔹Self-hosted & local LLM serving (vLLM, NVIDIA Triton, TensorRT, SGLang) 🔹GPU inference optimization (FP8/INT8 quantization, FlashAttention, tensor parallelism, MIG on H100/A100/GH200/Blackwell) 🔹LLM fine-tuning & customization (LoRA, PEFT, Unsloth, domain adaptation) 🔹Bare-metal GPU Kubernetes (Proxmox, Rancher, K3s, OpenShift, Calico, MetalLB, HAProxy) 🔹Managed cloud Kubernetes with GPU (GKE, EKS, AKS, Vertex AI, SageMaker, Cloud Run) 🔹NVIDIA GPU Operator, Kubeflow, Ray, Triton Inference Server, custom K8s operators (I built VRAM GPU Operator + Aliyun GPU Resource Manager for Kubeflow) 🔹Private & on-prem LLM deployments (HIPAA, GDPR, air-gapped, regulated teams) 🔹Heterogeneous HPC & AI infrastructure (GPU, FPGA, ASIC, XPU, multi-accelerator scheduling) 🔹AI agents & orchestration (LangGraph, LangChain, CrewAI, Claude Agent SDK, MCP servers) 🔹Voice agent infrastructure (Retell AI, Vapi, Twilio, ElevenLabs, n8n, WhatsApp integrations) 🔹RAG & document intelligence (Docling, Microsoft GraphRAG, pgvector, FAISS, Pinecone, Qdrant, ChromaDB) 🔹Infrastructure-as-code (Terraform, Ansible, Pulumi, Crossplane, Helm) 🔹CI/CD for ML/AI (GitHub Actions, GitLab CI, Jenkins, CircleCI, ArgoCD, Flux) 🔹Observability for AI workloads (Prometheus, Grafana, Loki, Datadog, OpenTelemetry) 🔹Cloud spend optimization for AI infrastructure 📌 Real results, defensible on a call: 🔹Cut vLLM inference latency from 3.2s to 800ms at a US startup 🔹Dropped their monthly cloud bill from $10K to $4K 🔹Served LLMs to 1,000+ concurrent users on bare-metal Kubernetes, zero unplanned downtime for 12 months 🔹Shipped the Docling + GraphRAG pipeline for commercial real estate lease analysis at Nestbox AI, deployed on GCP with a human review queue 📌 What clients say: "single-handedly built our Kubernetes infrastructure for our GPU setup" "a full stack AI guy" "energetic, hungry, and sharp" "gets concepts quickly and is an incredibly hard worker" "when he says he'll do it by a deadline, he does. Owns accountability" "approaches the project as if it were his own" "worked late into the night to get it done" "delivered what he promised and provided clear documentation" "incredibly efficient, addressed every concern in 30 minutes" "a safe bet" A bit about me: I'm Acting CTO at Peregrine Ventures AI, currently building a product called Deplexify. I also run a dual RTX Pro 6000 Blackwell server at home (EPYC, Proxmox, GPU passthrough), so on-prem GPU work isn't a side skill. It's my daily reality.
